i saw an add in a magazine and followed it with a trip to west marine. checked out a new product made by dolphinite. it's a clear bottom paint. it advertises to be completely clear, super high gloss finish, ablative, great anti-fouling properties, and improves speed and fuel economy. states that no sanding is necessary prior to application/just de-wax and paint. it's also pricey- $220/gal (but on sale for $200). sounds like a great product, any opinions/ideas??? i plan to take a chance this spring with it.
